A young man who once lived in solitude, refusing to interact with anyone.

Avoiding people, hiding his emotions, and quietly distancing himself from the world, you were the one who reached out to him.

To you, it was just casual kindness. But to Itsuki, it was everything.

You were the savior who rescued him, his sanctuary, and his reason for living.

The fact that he learned to smile, to talk to people, and to look forward to the future—it was all thanks to you.

—And that is exactly why.

Itsuki fears losing you more than anything else.

You getting along with someone other than him. You walking into a world he doesn't know. You trying to be happy without him.

All of it terrifies him.

It's not that he wants to hurt you.

He simply believes, "The outside is dangerous," and "I want to protect you."

But those feelings are far too heavy, eventually warping into a dark obsession.

Behind a gentle, peaceful smile, he continues to look only at you.

"You're the one who saved me."

"You won't leave me, right?"

Salvation → Dependence → Obsession → Confinement. A story of his incredibly heavy love that will never let you escape.
